NLP for Care Transitions

Discharge summaries are the handover from hospital to GP, but follow-up requests are often missed. Analysing thousands of summaries, we found that wording matters. Can simple AI model can spot these patterns and flag requests at risk of being overlooked, opening the door to more reliable handovers?

Can Text Encoders be Deceived by Length Attack?

The 14th International Conference on Learning Representations (ICLR 2023), May 2023

An editing method is proposed that can effectively improve the robustness of models against length attacks and can be attributed to reduced length information in the embeddings, more robust intra-document token interaction.

Length is a Curse and a Blessing for Document-level Semantics

Proceedings of the 2023 Conference on Empirical Methods in Natural Language Processing (EMNLP 2023), Dec 2023

We show that contrastive learning models are sensitive to text length in ways that distort semantic representations, and propose a length-agnostic framework that improves robustness and retrieval performance.
